IMO, throw the previous Central Atlantic recurve models out the window. 94L is moving faster and due W for the next few days. The Central Atlantic weakness may be strong enough to allow 94L to gain latitude but does not appear enough to send 94L fishing for now!
great, that is not what we want to see --- a system moving west like that with no recurve scenario . Hopefully it just dies.

Re: ATL : INVEST 94L
How much shear and dry air ahead for 94L? ... Starting to have doubts as well for further significant development. It is a large area, but if anything looking less organized. I wouldn't worry with the models since it's not developing anytime soon.

Re: ATL : INVEST 94L - Computer Models
I only post the model runs for formality,but we know that until there is a true LLC and the system developing,the models are wacked.

Well based on the CIMSS SAL analysis it doesn't look like dry air is much of a problem for it.

And that is what I am mostly worried about,comming from someone who lives in the NE Caribbean.

it shouldn't take a week to reach the islands. It could be there in about 4 days if it stays at the low latitude
However, this needs to speed up if it wants to develop... and speed up by about 5-8KT to catch up with the convection
